Specific embodiment
Below in conjunction with attached drawing, the present invention will be described in detail:
As shown in Figure 1, 2, a kind of compound core pipe present tube molding equipment, including the limit being commonly mounted on a platform or bracket
Hyte part, preset tube assembly and extruder (not shown), limit assembly include the limited block 1 of a rectangular shape, limit
Lateral direction penetrating is machined with the limit hole 11 for being set with hollow metal tube in the block 1 of position.Preset tube assembly includes mandrel 2, master
Support 3 and secondary support 4, mandrel 2 are coaxially disposed in limit hole 11, and 2 both ends of mandrel, which can relay to set, is being located at limited block 1
4 top of main support 3 and secondary support.Main support 3 is equipped with the motor 31 coupled by shaft coupling with mandrel 2.It sets with one heart
It sets so that the plastics tube thickness that is molded by of mandrel 2 and metal intertubular space is uniform.
In production, firstly, by metal pipe sleeve inside limit hole 11, while mandrel 2 being passed through inside metal tube simultaneously
Felt relieved by main support 3 and the secondary adjusting of support 4, the adjusting of support can for screw thread, movable casing or it is similar can
Realize that position adjusts the device of positioning to realize.Hereafter, the plastic raw materials of molten condition are perfused into metal tube by extruder,
Such as PP, PE, while mandrel 2 keeps rotation under the drive of motor 31, and the rotation of mandrel 2 at this time can be by the plastic raw materials band of injection
Realize effective, complete filling in the dynamic metal tube depths that enters.Hereafter, plastic raw materials are as cooling is in semi-solid preparation, the rotation of mandrel 2
Being adhered when making it realize shaping, bright and clean effect to the plastic raw materials released with it, and can prevent from solidifying.Finally, in plastics
After raw material is fully cured, extraction mandrel 2 obtains composite metal-plastic pipe.
As shown in figure 3, in the present embodiment, secondary support 4 includes support block 41, has only to support at the top of support block 41 and is supported on
Bearing surface 42 below metal tube.Bearing surface 42 is V-shaped, and v-shaped structure makes mandrel 2 have self centering effect when being placed on it
Fruit, 2 axis of mandrel is Chong Die with the symmetrical plane of V-arrangement, guarantees that it, with good centering effect, will not lead because of the deviation of axis
Cause quality of production decline.The support of V-arrangement simultaneously will not influence the rotation that motor 31 drives lower mandrel 2.
In the present embodiment, mandrel 2 is hollow copper tubing, and support block 41 has upwardly-extending baffle far from 1 side of limited block
43, baffle 43 is used to limit the horizontal position of mandrel 2.The first heat exchanger tube 51 of U-shaped hollow tubular is outward extended on baffle 43,
First heat exchanger tube 51 is threaded through inside mandrel 2.Through-hole equipped with multiple perforations with limit hole axis direction level in limited block 1
12, the second heat exchanger tube 52 of straight line hollow tubular is equipped in through-hole 12.52 copper pipes of first heat exchanger tube 51 and the second heat exchanger tube.
In the present embodiment, the first heat exchanger tube 51 and 52 both ends of the second heat exchanger tube are connected with circulating pump (not shown), follow
Ring pump is connected with heat exchanger (not shown).By circulating pump, can be formed inside the first heat exchanger tube 51 and the second heat exchanger tube 52
Water circulates, and the heat exchanger in the present embodiment is axial flow-type heat exchanger, connects with heat exchanger tube and connects with circulating pump formation,
Heat exchanger realizes that the heating to the moisture of circulation cools down by exchanging with extraneous heat, in turn, the first heat exchanger tube 51 and second
Heat exchanger tube 52 can be heated and be cooled down to mandrel 2 and limited block 1 and metal tube.Advance in the plastic raw materials of injection melting
Row heating can make plastic raw materials just not cool and solidify agglomeration when contacting metal tube and mandrel 2, to improve production matter
Amount.It is cooled down after the plastic raw materials of input melting, the speed of cooling and solidifying can be improved, and then improve production efficiency.
In the present embodiment, baffle 43 is fixed in support block 41 by the way that bolt is removable.To facilitate the installation and the of metal tube
The grafting of one heat exchanger tube 51 is installed.
In the present embodiment, there are horizontal guide rail 32, main support 3 is movably connected to guide rail 32 for main 3 lower section of support,
To facilitate main support translation under manpower or the effect of other power after the completion of production to extract out and then be convenient for the extraction of multiple tube.
In the present embodiment, 42 surface of bearing surface is covered with wearing layer made of nylon pasting or being spirally connected, so as to subtract
Abrasion when itself and mandrel 2 contact less.
In the present embodiment, 11 inner wall of limit hole is connected with tread plate 111 made of more rubber pasting, and tread plate can
So that metal tube has more stable locating effect in limit hole 11, especially in 2 rotational action of mandrel, so that metal tube
It will not be driven together, guarantee the stability of production.
Only preferred embodiments of the present invention will be described for above embodiments, not to the spirit and scope of the present invention
It is defined, without departing from the design concept of the invention, ordinary people in the field makes technical solution of the present invention
All variations and modifications, each fall within protection scope of the present invention, the claimed technology contents of the present invention, whole note
It carries in detail in the claims.
